FOLDING BOX.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed November 11, 1904, Serial No. 232,334.

'Box, of which the following is a specification.

My invention has for its object to provide an improved knockdown orfolding box especially adapted for use for delivering groceries andother articles which are put up in small packages or which are to bedelivered in bulk.

The improved box in its preferred form is illustrated in theaccompanying drawings, wherein like characters indicate like partsthroughout the several views.

Figure 1 is a perspective view showing the improved box set up for use.Fig. 2 is a perspective view showing the improved box folded into flator knockdown form. Fig. 3 is a detail in section on the line m m of Fig.1; and Fig. 4 is a detail in perspective, illustrating the constructionof one of the hinge members.

The numerals 1 and 2indicate the four sides of the box, and the numeral3 indicates the folding bottom thereof, which bottom is hinged to one ofthe side members lfor folding movements against said side member, towhich it is hinged. The side members or plates 2 are shown as providedwith the usual hand-holes 1, which adapt the box to be lifted and firmlyheld by the hands. At diagonally opposite corners of the box the sideplates 1 and 2 are hinged for folding movements by rectangular hingemembers 5, formed by bending a rod into rectangular form. The horizontalupper and lower sections of these hinge members 5 when the box is set upextend diagonally across the corners of the box, and the vertical legmembers thereof are pivotally attached to the side plates 1 and 2 inwardof their abutting edges by metallic clips or hinge-loops 6, the ends ofwhich are passed through said side plates and are clenched on the innersurfaces thereof, as best shown in Fig. 3. 'The said Vertical portionsof the hinge members 5 are preferably countersunk, atleast partially,into the side plates, to-which they are attached. At the otherdiagonally opposite corners of the box the side plates 1 and 2 arepivotally connected for folding movements by rectangular hinge-rods 7the horizontal portions of which are preferably bent to form rectangularoffset sections 7,

that are rigidly secured to the side members 1 by metallicanchoring-clips 8, that are riveted or otherwise rigidly secured to saidside members 1 at the upper and lower edges thereof. One vertical leg orportion of each hinge member 7 is also preferably secured to one of thesaid side members 1 by means of the clips 6,'c'onstructed as beforedescribed. The other vertical leg portions of said hinge members 7 arepivotally secured one to each side plate 2 by clips 6 of the samecharacter as those applied to connect the hinge members 5 to the sideplates. These hinge members 7 pivotally connect the side plates 2 to theside plates 1 at offset points, so that when the box is folded, as shownin Fig. 2, space will be left between the said side members 1 and 2 intowhich the bottom plate 3 of the box may be folded, as shown in said Fig.2.

\Vhen the box is setup for use, as shown in Fig. 1, the corners thereofare rigidly braced by the hinge members 5 and 7. When the box is folded,as shown in Fig. 2, the hinge members 5 turn into the same planes as theside members 1 and 2, which they pivotally connect.

The construction described, while strong, durable, and generallyefficient for the purposes had in view, is of small cost.

From what has been said it will be understood that the box described iscapable of modification within the scope of my invention as herein setforth and claimed.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. A folding box having its four sides connected for toggle-like foldingmovements by means of hinge members, the hinge members of diagonallyopposite corners being of rectangular form and arranged to completelyembrace the corners of the box and having parallel legs attached to thesides of the box inward of their vertical edges, whereby the sides ofthe box may be folded together and whereby when the box is set up, itscorners will project through the said rectangular hinge members,substantially as described.

2. A folding box having its four sides connected for toggle-like foldingmovements, by means of hinge-rods bent to form parallel legs, the saidhinge-rods at two of the diagonally opposite corners of the box beingjournaled to the abutting portions of both .of the sides which theypivotally connect, and the hinge-rods at the other two diagonallyopposite corners being rigidly secured to one of the sides which theypivotally connect, and being jou'rnalecl to the other of the said sides,substantially as described.

3. The combination With a box made up of the four sides 1 and 2, of thehinge-rods 5 bent to form parallel legs applied to pivotally connect thesides at two of the diagonally opposite corners of the box, said rodsbeing journaled to said side Walls, by clips 6 located in- Ward of theabutting edges of said sides so that the horizontal portions of saidhinge-rods 5 extend diagonally across the corners of the box, When thebox is set up, the rectangular hinge-rods 7 at the other diagonallyopposite corners of the box, rigidly secured to the sides I 1 andjournaled to the sides 2, by means of clips 6, located inward of theedges of said sides 2, so as to afford offset hinges, and, a box-bottomhinged to one of said sides 1, substantially as described.

In Witness whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses.

ISAK WIGREN.
